The
WIZARD ARC® Controller for liquid chemical day tanks and dry
chemical feeders is designed to automatically refill your day tank
or hopper from bulk supply when the tank or hopper runs low. Also
included in the controller are powerful chemical accountancy features
that accurately monitor chemical usage, level and feed rate.

A large,
easy to grasp HAND-OFF-AUTO (HOA) switch provides operators with
an interface to fill the day tank/hopper automatically or manually,
or to shut off the transfer operation. The WIZARD ARC Indicator/Controller
provides convenience and safety in a single package. Operators can
review chemical inventory and consumption as well as replenish supplies
with a single instrument. Automated operation minimizes personnel
contact with chemical and the chance of failure to refill. Fail
safe operation prevents tank/hopper overfilling. A "MAX DAILY
USE" alarm prevents your system from feeding more than a set
amount of chemical within a 24 hr. period.

The
principal of operation for the WIZARD ARC utilizes weight, one of
the most accurate and reliable forms of measurement. By monitoring
the weight of the day tank/hopper, the WIZARD can turn on a transfer
pump, valve or screw feeder to refill the day tank/hopper when it
is low. When the tank/hopper weight reaches the "FULL"
set point, the WIZARD turns the transfer device off. Two additional
set points can be used to activate Low and High Level Alarms. When
refilling the day tank/hopper, the WIZARD automatically preserves
consumption data to provide accurate accounting of the amount used,
feed rate and days until empty. Monitoring by weight is non-intrusive
and non-contacting so the potential for leaks or failure due to
fouling is virtually eliminated.
